Exterior & Interior Wall Intersecting Issue

[Jim]

The exterior and interior walls are not intersecting properly on my drawing. I am new to Archicad so this is most likely a simple fix but I don't want to waste anymore time on it so here I am.

I seen a few other posts talking about Building Material and Intersection Priority but its either not working or I'm not adjusting these settings properly.  

Any help is much appreciated.

The Building Material you have used for the insulation element of the wall needs to have a higher priority than any element of the interior walls. Where two composite walls intersect the layers of the composite wall which have a higher priority will cut those with a lower priority.

If you upload some screenshots of your composite setting for each of the wall types you have used it will be easier to help you adjust them. Also, if you select one of your composite walls and then open the Building Materials settings under Options, Element Attributes, Building Materials, all those in use by the selected composite will be highlighted green to make it easier to find and adjust them. You can then order the list by the priority setting and adjust the values.

Thank you! That worked!

Regarding the one spot where you internal wall did not penetrate your external wall, make sure your Reference Lines are intersecting consistently.
